Nellie Ohr told lawmakers in October that one of Fusion GPS’s sources was a Ukrainian parliamentarian whose government has accused him of illegally meddling in the 2016 U.S. election.

Ohr, a former Fusion GPS contractor, testified that Serhiy Leshchenko was a source for the Democrat-funded opposition research firm.

Leshchenko was the leading force behind the release of the so-called “black ledger,” which accused Paul Manafort of receiving illicit payments from the Ukrainian government. The ledger led to Manafort’s firing from the Trump campaign, but its validity remains in dispute.

On Dec. 11, 2018, a court in Kyiv ruled that Leshchenko’s release of information about Manafort “led to interference in the electoral processes of the United States in 2016 and harmed the interests of Ukraine as a state.”

Kiev officials are scrambling to make amends with the president-elect after quietly working to boost Clinton.

Ukrainian government officials tried to help Hillary Clinton and undermine Trump by publicly questioning his fitness for office. They also disseminated documents implicating a top Trump aide in corruption and suggested they were investigating the matter, only to back away after the election. And they helped Clinton’s allies research damaging information on Trump and his advisers, a Politico investigation found.

A Ukrainian-American operative who was consulting for the Democratic National Committee met with top officials in the Ukrainian Embassy in Washington in an effort to expose ties between Trump, top campaign aide Paul Manafort and Russia, according to people with direct knowledge of the situation.

The Ukrainian efforts had an impact in the race, helping to force Manafort’s resignation and advancing the narrative that Trump’s campaign was deeply connected to Ukraine’s foe to the east, Russia. But they were far less concerted or centrally directed than Russia’s alleged hacking and dissemination of Democratic emails.
